A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?Analysis of common faults of oil immersed transformer:St clement,According to statistics, to occupy the main global technical position, the transformer industry depends on two key data, commodity volume and voltage level. As early as & ldquo; Eleventh Five Year Plan; In the early stage, China has been a powerful country in the production, manufacturing and application of dry-type transformers all over the world, dry-type transformers are mostly used in & ldquo; Fireproof and explosion-proof type & rdquo; It is easy to use in large and medium-sized engineering buildings and multi-storey buildings; The oil immersed transformer because of & ldquo; Accident & rdquo; There is likely to be oil or leakage after fire, and most application places leading to fire accidents are easy to choose in large and medium-sized engineering buildings and multi-storey buildings;BektemirWhen the transformer is out of phase,St clementDry type transformer model making, if the second phase is blocked, there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked, the sound will not change, as in the case of the second phase. There are three reasons for phase deficiency:What is the important role of power transformerOutdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling, it is necessary to resolutely prevent the invasion of dirt such as rain, snow, wind and sand.

Difference between dry-type transformer and oil immersed transformer:It is understood that in China, S Series lossless distribution transformers were selected in China to replace the high energy consumption transformers of jb- and jb - Specifications operating in the power network at that time. Since the th century, urban power grids have been transformed all over the country, and S series distribution transformers have been used to replace S Series. In recent years S and S commodities are gradually selected in large quantities in the transformation of urban and rural power networks in China, and their full load loss is % - % less than that of S transformer.The flange surface is uneven, the tightening bolts are loose, and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.Direct material,Oil leakage of porcelain pot and laminated glass oil level gaugeThere are many connection groups of dry-type transformers, and the selected structures and connections are also different. Then, what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, resulting in short circuit between coils, two-color short circuit or short circuit on the ground, resulting in the ignition of power transformer. Therefore,Plug in the power with full load first and overload is not allowed in the whole process of operation.

What is the reason for the shutdown of power transformer?Quality documents, observe and detect that the input and output voltage meets the regulations. At the same time, ignition, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.It is understood that in China, transformers have experienced the whole process of replacing many series products such as sss. As early as the middle and late s, S Series lossless distribution transformers were selected in China to replace the high energy consumption transformers of jb- and jb - Specifications operating in the power network at that time. Since the th century, urban power grids have been transformed all over the country, and S series distribution transformers have been used to replace S Series. In recent years, S and S commodities are gradually selected in large quantities in the transformation of urban and rural power networks in China,St clementMain components of oil immersed transformer, and their full load loss is % - % less than that of S transformer.The flange surface is uneven, the tightening bolts are loose, and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.St clement,Note: in the whole process of safety patrol inspection, the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself, terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal, significantly expanded, or there is local sound, the cause shall be found immediately and certain effective measures shall be taken. If necessary, the load can be reduced or the operation of the transformer can be stopped.Dry type transformer manufacturerFor no-load impulse closing of transformer, pay attention to the following matters:
